L :ind water under n suitziqble head is die?- charged through said pipe, and the latter being 'manipulated in such manner as to "nsh away the earth from under the bottom of the form o. The right :regulan-portion 3 of the jet pipe, 1, also serves esja ha'ndle, facilitating,r the manipulation of'the letter. The soitwashed nwziy from underthe form 6 is disttharged, together lwith the Waiter', through the spout 4 of the inner s'hell 4, as indicated by the arrows in the lower part :i nd :it Z; in Fig. the arrow, a, in the Swine ligure, represents the inflow of Water through said jet pipe 1 As the soil is washed from-under the form the weight of thev concrete filling l1 will cause the latter to sink` in the cavity formed in the soil. When theform has been so tur-sunk into the ground that its upper end is almost flush therewith tl'ie`1torin is extended upward by adding further sections to the outer and inner shells. This muy be conveniently done us shown in Figs. and 6, the ends of the outer shell being;- connected by means of butt strips 8 riveted in place by rivets 14. Next an upper section ot the inner shell 4 is fas: tened in place. The extension of the form so built is then also filled with concrete, and the hydraulic process of sinking' the pile is continued. ln Fi the vpile is shown as sunkits full depth, and as having' the inner shell 4 also filled 'With concrete, 12, which is the inil step in the construction of ,my pile. In someeases the filling of the outer form G, :is well as the inner shell 1L, in stead of being of concrete maybe sund, or other material which will peek sufficiently to impart solidity to the pile as n Whole, and render it .adopted to support its load.

One of theiinportent features of my improved method is that :ill the Concrete used in the making or' the pilemiiy be inspected, u'hieh insures uniformity of the mass.
